Passing array from JavaScript to PHP without losing code functionality

Question

Using this piece of code I can list all the file URLs inside the Folder_A and Folder_B and Folder_C :

<?php
function getDirContents($directories, &$results = array()){

    $length = count($directories);
    for ($i = 0; $i < $length; $i++) {

    $files = array_diff(scandir($directories[$i]), array('..', '.'));;
    foreach($files as $key => $value){
        $path = $directories[$i].DIRECTORY_SEPARATOR.$value;
        if(is_dir($path)) {
          getDirContents($path, $results);
        } else {
          $directory_path = basename($_SERVER['REQUEST_URI']);
          $results[] =  'https://' . $_SERVER['SERVER_NAME'] . str_replace($directory_path, "", $_SERVER['REQUEST_URI']) .$path;
        }
    }

    }

    return $results;
}


$directories = array("Folder_A", "Folder_B","Folder_C");

echo json_encode(getDirContents($directories));

And using the JavaScript code below we can log them in the console (And have access to them via javascript):

$(document).ready( function() {
        $.ajax({
            type: 'POST',
            url: '../test.php',
            data: 'id=testdata',
            dataType: 'json',
            cache: false,
            success: function(result) {
            console.log(result);
            },
        });
});

I just want one simple thing that I can't find a solution by myself:

How can I define the Folders inside javascript instead of having them in PHP?

I mean instead of having this inside PHP code:

$directories = array("Folder_A", "Folder_B","Folder_C");

I want to have this in Javascript:

let directories = [ "Folder_A", "Folder_B","Folder_C"];

And return the same functionality.

Pass the directories as part of the data: parameter.

$(document).ready( function() {
    let directories = [ "Folder_A", "Folder_B","Folder_C"];
    $.ajax({
        type: 'POST',
        url: '../test.php',
        data: {id: "testdata", directories: directories},
        dataType: 'json',
        success: function(result) {
            console.log(result);
        },
    });
});

Then in PHP you can use $_POST['directories'] to get the array:

echo json_encode(getDirContents($_POST['directories']));

I'm not sure why. Check the Network tab of the console to see what's being sent and received.

I think space causes the problem, If I have Folder A the code doesn't work...if I have Folder_A code works fine?!!
